I just tested the TDS (total dissolved solids) of various water sources with the TDS meter that came from Dave's Reefpure. Here are the following results:
1. tapwater 35 ppm
2. saltwater aquarium 445 ppm
3. freshwater aquarium 180 ppm
4. RO/DI water 0 ppm
What's interesting is that I tested the water in two containers that I filled earlier today from the RO/DI reservoir and one read 35 ppm while another one read 70 ppm!
I poured out the 35 ppm water into the freshwater tank and refilled it with the siphon pump attached to the RO/DI reservoir and it read 0 ppm. I can only think of two things that could be causing this:
1. 1 gallon container had some solids in it that were dissolved by the RO/DI water
2. Solids are falling into or leaching from the RO/DI reservoir over time.
I hope it's number 2!
I'm getting 20 hermit crabs, 3 urchins and ten tiger trochus snails from eTropicals tomorrow morning. I hope they do a good job on the nuisance algae in the 50G. I'm particularly interested in seeing how the Diadema urchin and the tiger trochus will do. I only ordered from eTropicals after extracting the large Sally Lightfoot crab and putting it in the sump at work. I used the tall glass trap with food at the bottom. The crab is attracted to the food and goes to the bottom of the glass, but the sides are so steep and slick, it can't get out! I really love the build your own feature on the eTropicals Web site.
Took out the feather caulpera last night from the 29G refugium since it had a funny color.

It looks like there's some lateral line regression on the blue tang although he eats the most of any of the fish. Maybe I should get him some nice frozen food to eat. I'm trying to drip kalkwasser in the morning and evening in order to really keep up the calcium levels in the tank. 3 liters (two full Aquadose containers) of drip a day is a little bit more than the evaporative rate from the system right now, so I'll make sure I'm not dripping too much. I am adding a very concentrated mix of kalkwasser, so I think I am affecting the calcium levels in the tank, as evidenced by the coralline algae growth.

Aaaah! Hair algae is still growing back in the 50G. I'm going to follow these procedures:
1. No trace element additions except for strontium
2. Lighting cut to 4 hours a day in 50G.
3. Calcium supplementation via Aquadose with 1 tsp of Kalkwasser mix and 1500 ml of RO/DI water every morning. To make this mix, I first fill the Aquadose with 200 ml of water, add the Kalkwasser mix, and then shake the Aquadose. I then add the rest of the water and let it drip. This should provide some really fresh Kalkwasser for the tank.
4. Empty skimmer cup every other day
5. 300 ml of carbon a week
6. 40 liter water change a week
